[PATCH] D136078: [RFC] Use-after-return binary metadata.

[Dmitry Vyukov via Phabricator via cfe-commits]

dvyukov added a comment.

Marco, does this look reasonable? Any high-level comments?

There are lots of plumbing to add a new flag and integrate a new pass, so you can look only at:
llvm/lib/Transforms/Instrumentation/SanitizerBinaryMetadata.cpp
llvm/lib/CodeGen/SanitizerMetadata.cpp

As far as I understand the stack layout is only known in machine passes via MachineFrameInfo,
so I had to add a machine pass.
